I'm not using an XA connection factory but a MQQueue connection factory.
And I still does not understand why i cannot connect to my local Websphere MQ server 5.3 with my 6.0 jars  |

Like I said, I would not trust my 6.0 to connect to a 5.3 below CSD11.
Certainly not below CSD6. I believe you're at CSD1....
If you have server and client on the same box your client installation NEEDS to be at the same level as the SERVER installation. (because of transport = bindings). This includes your java client installation. You cannot run different MQ components (server/client) at different levels on the same machine.
Don't even wonder about applying maintenance. Just upgrade the installation to a supported version....

Ok, so i updated my server to the latest CSD14
C:\Documents and Settings\user>mqver
Name: WebSphere MQ
Version: 530.14 CSD14
CMVC level: p530-14-L071214
BuildType: IKAP - (Production)

I'm not using 2 mq in the same box : My local server is a 5.3 server, and i have a remote server with MQ 6.0 installed. I just change the jars when i have to use one or the other version.
So i've done another test using 6.0 jars (com.ibm.mq.jar, connector.jar, com.ibm.mqjms.jar and dhbcore.jar). I try to connect to my MQ local server 5.3 CSD 14 with the following code
| Code: |
MQQueueConnectionFactory factory = new MQQueueConnectionFactory();
try {
factory.setQueueManager("QMGR");
factory.setTransportType(JMSC.MQJMS_TP_BINDINGS_MQ);
connection = factory.createQueueConnection();
}
|
but still having a problem

This problem does not appear if i use 5.3 jars... but I don't want to change jars depending of the MQ version i have to connect to !
Any solution ?
Thank you |

So which part of "You cannot run different MQ components (server/client) at different levels on the same machine" did you not understand?
with a JMSC.MQJMS_TP_BINDINGS_MQ transport you are indicating that you do a "bindings" connection to the server residing on the same box.
Now if that server is 5.3 CSD14 you are SOL. BECAUSE once more You cannot run different MQ components (server/client) at different levels on the same machine
Have fun

Ok, I'm sorry. I'm not fluent in english and i use a dictionnary to translate in english, so sorry if sometimes i misunderstand you.
I was thinking that you were telling me that i can't install 2 MQ series server in the same box.
PeterPtkay told me that there was backward compatibility, so i was thinking that i can use different library in the same machine

| There is compatability between those versions of MQ. If your problem went away when you changed versions that's purely coincidental and not the root cause for a 2046 MQ Reason Code. |
but it should be for remote connection only....
I'm surprise with that
| fjb_saper wrote: |

Because if I use the native library com.ibm.mq.jar and connector.jar with this code
| Code: |
MQEnvironment.channel = null;
MQEnvironment.hostname = null;
MQEnvironment.port = null;
MQQueueManager QManag = new MQQueueManager("QMGR");
|
i don't have any error and i can use jar 5.3 or 6.0 in the same box to connect to a local 5.3 MQ series server
So it is forbidden to use JMS library to connect to local mq series 5.3 with Jar 6.0 ?

Connecting to a local qmgr in bindings mode using java or JMS involves more than just jar files. You may notice that you also have runtime libraries (.dll/.so) in the <mqinstall>/java/lib path. These are specific to the server version. This is why you should allways use the same version as the server version when you connect to a server in "bindings" mode.

Ok, i just feel strange that using object MQQueueManager it works and does not work using MQQueueConnectionFactory.createQueueConnection(), as they will ask the same dll ....
So if i want that my application can either connect to a local server and remote server:
- I will have to provide jars when user want to connect to a remote server
- Or add the <mqinstall>/java/lib path to the classpath for a local connection
Thank you for your help |
